CUP-PABTRY-MAKING MACHINE.

Specification of Letters Patent.

Patented Feb. 18, 1919.

Application filed July 10, 1918. Serial No. 244,254.

To all whom it may concern:

Be it known that I, ALnEn'r E. Dm'rnulon, a citizen of the United States, residing at Washington, in the District; of Columbia, have invented certain new and useful Improvements in Cup Pastry Making Maduring the period of ejection from the machine.

More specifically thejnvention provides a, trimming tube through which the article is "passed to efl'ect a separation of the excess better from the article, the trimmings being collected and removed by a'suction mechanism whereby the same, may be kept" clean and sanitary and in condition for further use if desired, while means are provided for passing the article through the trimming tube by pneumatic action and delivering it from the machine either into the boxes or receptacles therefor or onto a table or other receiver, and preventing the article from being pushed up out of the trimming tube on t e recessional movement of the pusher. In addition to the cooling of the article and passing it t'lTrougtPthe trimming tube, the air currents also serve to keep the trimming tube cool so that its knife edge will not loseits temper. l i i In its more detailed nature, the invention is a modification of the trimming and delivery structure found in my copcnding application filed. October 1, 1917, Serial No. 194,194.

In the drawing the figure is a vertical Section of a molding unit and the trimming and delivering mechanism located at. the extructing station, the article having been forced into the trimming tube and brought under the influenceof the ejecting air currents, while the pusher (core) is ready to be wlthdrawn from the trimmingtubc.

In the drawing. l-l represents the female mold sections and 2 indicates the core of u molding and baking unit such as is shown in my copending application aforesaid. 4 represents the trimming tube whose knife edge 3 cuts the excess batter from the article as the article is pushed through the mouth of the tube, the trimmings falling into the receiver 5 and being withdrawn therefrom and delivered to a definite location by sue tion applied through the duct 6 in any approved and usual way.

7 is an air pressure chamber into which compressed air is delivered by a pipe 8 from any suitable source. The wall of the throat of the trimming tube has one or more unnu lar series of ports 9 downwurdlv and inwardly directed toward the'nxis of the tube .whereby the uir from the clumiber 7 will be delivered in a conical jet-sheet, the tocal point of which lies preferably along the axis of the trimming tube. It will be noticed that the jet-sheet. first impacts the outside of the article 11 nd holds it against following or sticking to the core 2 when the same is used as the pusher and then as soon as the mouth of the article passes the up ermost' set hf ports 9, the jet-sheet wil be i'ocuscd into the article and cause it to pass oi'lt of the throat or duct 4 and be delivered into the box 10, or other suitable receptacle provided therefor. Thus, it will be that the air jet. in the throat or duct/of the tube 4 first is blown on the outside of the article 11 and is then directed on the inside of the same, thus tending to cool the article throughout as well as serving to prevent the article from following the pusher core 2 out 'of the tube 4.

Of course, the pressure of thc air'in the chamber 7 will be suitably regulated so as not to injure the article or deliver it with too much form-,a lighter pressure, of course,

being required where gravity is used to as sist delivery than would bethe case were the delivery made horizontally or at an upward inclination as may be desirable when it is desired to deliver the article onlo :1 table or in a. box laid on the side at some distant point from the trimming tube. it

being obvious that the duct -l can lumadc it is thought the completir-ruistrucliol'i, op-

oration and advantages of myinvention Will be clear to those skilled in the art and I desire it understood, howeyer. that mod1fi cations of the invention and slight changes in the details of construction, arrangement the appended claims.

What I claim is:

1. In a machine of the class described wherein is provided sectional modes and cores therefor, and a trimming tube into which the art cle is delivered by the core; the combination with the trimming tube and thee-ore, of means distinct from the cutting edge of the trimming tube for holding the article against core-following movement after being trimmed.

2. Ina machine of the class described wherein is provided sectional molds and cores therefor, and a trin mii'ig tube into Which the article is delivered by the core; the combination with the trinnning'tubc and th core, of pneumatic means for restraining the article from pulling baclcout of the trimming tube on the movement of the ore.

3. In a machine of the classulescribed wherein isprovidcd sectional molds and cores thcrcfor,-and a trimming tube into which the article is delivered by the core; the combination with the trimn'iing tube and the core, of means for directing a current oi air inside the trinn'ning tube in a direc tion away from the entrance of the same to deliver'the trimmed article through the tube.

4. In the artof cup pastry manufiu'tureia trimming tube into which the article to be trimmed is placed, means for pushing the article into the tube to remove the excess material from the article, a suction-.device for conveying the trimmings from the'tube and pneumatic means for delivering the trimmed article from the tube.

5. In a machine of the class described wherein. is provided molding and bakingunits, anda trimming tube into which the molded and baked article is delivered from.

the molding'and baking units; the combina-v tion With-the trimming tube, means for passing the article through the mouth of the tube to detach the excess batter, means for separately collecting the trimmings and the trimmed article and delivering the same from the machine and cooling the trimming tube-and and the trimmed article.

6. A trimming tube having a mouth witha trimming edge, a trimmingscollecting pan embracing the tube, means for producing a downwardly directed coniform air jet withinthe tube to force the article through the-tube.

recession-a1 placed, means for pushing the and inwardly directed air ports in its wall belowthemouth' of the tube, and means for delivering air under pressure through said ports into the tube.

9. A trimming tube, an air pressure chamber around the tube. and ports for deliven inn; the air from said chamber into the tube.

10. A trimming tube, an air pressure I chamber and atrimmings collecting pan outside said tube, means for conveying the trimmings from said pan, means for delivering theair from said chamber into the tube in'th form of a conical jetsshect directed toward the exit'end of the'trlmming tube.

11. A trimming tube, an air' pressure chamber and a trimmings colleetingpan outside said tube, means for conveying the trimmings from said pan, means for'delivering' the air from said chamberi'nto the tube in the form of a conical jet-sheet directed-toward theexit: end of the trimming tube and focalized along the 'axial line of the trimming tube. i I

12. A trimming tube, an air pressure chamber and a trimmings collecting pan outside said tube, means for conveying the trimmings from said pan; means for delicering the air from said chamber into the tube adjacent to the entrzince thereof to impact theoutside of an article restingon the mouth of the trimming tube.

139A trimming tube,-an air pressure ering the air from said ehai'nbc iuto the tube: in theform of a conical jet-sheet "directed toward the exit end of the trimming tube and sufliciently close to the entrant end of the trimmin tube to impact the outside of an article he (I in themouth of the tube and to engage the article on the inside ivhen the same has been trinun ed and has passed by the topot the jet-sheet;

tube in which. the article'tofbe trimmed is article into the tube'to remove the excess material from the article, and pneumatic means for 'delivr ering' the trimmed article through the tube.
